* i This invention relates to typographical orembodiment except in sofar as; such liinie machines, such as linotype machines of the generalorganization represented in'Letters Patent of theUnited States, No.436,532,

to O. Mergenthaler, wherein circulating the order in which theircharacters are to appear in print and then assembled in line, thecomposed line transferred to the face of a mold, themold filled withmolten metal to form a slug or linotype against the mat,

rices which produce the type characters thereon, and the matricesthereafter elevated and returned through distributing mechanism to themagazine from which they started. More particularly, itrelates to thatclass of linotype machines equippedwith a plurality of magazines mountedin-or "carriedbyv a so-calledfshift frame, which is movable upwardly anddownwardly in the j machine frame tov bring one or another of themagazines into operat1ve relation to the assembling and distributingdevices. In the commercial machines of this type,'the shifting ofthemagazines is accomplished by.

means of screw mechanism controlled by a handcrank .conveniently'locatedat the front of the machine. Vhile this arrangement-is thoroughlypractical, the operation has always been slow and tedious and more orless laborious. V

The present invention contemplates the use of power for raisingandlowering the magazines, and the'mechanism herein provided notonlypresentsmany advantages over prior devices but is-particularly valu1 able asa commercial proposition, owing to its ready applicability tothe. standard and outstanding machines. In the preferred embodimentillustrated,the inclined shaft ordinarily employed for rotating themagazine elevatingscrew is operatively connected to aucompactself-contained reversing gear mechanism which is arranged at thefront ofthe machine and is driven directly by the fore-and-aft assembler driveshaft commo to al] linotype machines. v

In the accompanying drawings, the inven tion has been shown merely-inpreferred for-m and by way of example, and obviously many changes andvariations may be made therein and in its mode of adaption which wi lstill be comprised within its spirit. It is to be understood, therefore,that the invention is not limited to any specific form tation's arespecified'inthe claims. Referring to the drawings;

The parts so fardescribed, except as hereinafter specified, are or'may bethe same'inform and mode of operation as those embodied in the commercial ltfodel slinotype and in themselves cons stit-ute no part of this invention. 1

According; to the present'invention, the

' raising and lowering of the magazines is accomplished by means of areversible gear .mechanism which is driven directly by the assemblerdriveshaft G before mentioned, and which isjcontrolled by a positiveclutch "device eonveniently located'adjacent the key board B. As shownin Figs- 1, 3 and 6, the proposed'gear mechanism issupportedin a castiron bracket L having an upright'portion L and areal-ward extension Lthe latter serving as a bearing for, the forward horizontal extension Fof the lay shaft F Preferably, the bracket-Lis secured to the front sideof the intermediate: bracket 0 framework.

upright inclined shaft L also journaledfin the bracket L. At its upperend; theshaft L is provided with a bevel gear L keyed thereto andmeshing with a corresponding driving gQELIiG HIOUIltBd OII the fore andaftshaft G in front of the assembler drive pulley- G Motion istransmitted to the lay shaft F fron'i the fore and aft shaft G and gearG by a clutch L preferably of the jawior claw variety, which is splinedto the horizontal extension F between the reversing gears L L and isadaptedby a slight axial movement in one direction or the other toengage corresponding claw members VL' L fixed to said gears 'respec-,tively. 'As best shown in'Figs. 3 "and 5,'the

operation of the clutch is effected by means 'of a'fork L which engagesan annular groove or recess in the clutch and is eccentrically attachedto a short rock shaft'L allowed to turn freely onthe shaft extension Fthe bracket L and arranged to engage/a corresponding recess in the rockshaft L yieldingly in such disengaged or neutral position.

Conversely, when the control handle is thrownforwardly, the clutch L The parts A detent L 7 (Fig. 3) seated in i -maybe employed to maintain the clutch- It will now be seen that when thecontrol handle L 4 is thrown backwardly', V

7 plate F While a aw or claw clutch; such as; shown, is preferable tothoseof other types on account of its delicate control; it; isconsidered-advisable to incorporate in' the proposed mechanism some sortof friction or slip joint-which will relieve the parts of unduestrainiii-overcoming the inertia {of the magazines and shift frame; and atthesa'me time permit -the-= magazine selected to be properly arrested inoperative position by the banking of its aligning lugs A on; top of thegauge bars J, J as before described. Such' a contr-ivance might bearranged 3 at any convenient point in the train of connections betweenthe elevating screw and the driving gear G but in the present insta'nce,it is applied to the inclined portion-of the lay shaft F (which is cutin two for the purpose) in the form of a friction coupling whichcomprises a pair of circular disks F,

F (see-Figs.- 1 and 2') secured to the meeting en'dsof the two shaftsections, and a spring-pressed detent F mounted in the plate F andengaging one or another of several recesses F -formed in the opposing Aswill be obvious without furtherdescription; if the load should exceedthat for which it is adjusted to carry,-the detent F will merelybefor'ced out of the slip.

Such means, as best shown in Fig; i, consist of a clutch member Gslidably mounted on the shaft G and a corresponding clutch member Gsecured to the gear G the member G beingsplined to the shaft G by a pinand slot connection G G; and adapted when moved rearwardly to engage themean berG. a In this COI11]6OUO1],-1t willbe noted by reference'to Fig.4 that the gear GE is loosely mounted on the shaft G and is onlyconnected thereto when the clutch members are enga ec. The movement ofthe'clutch member 6 into and out of engagement-with the gear G iscontrolled by a push and pull rod Gr formed at its inner end with an annular groovev G wherein engages the pin magazines be selected for'use,the kn-ob G is first pushed in to connect the reversing mechanism withthe assemblingdrive shaftG and given a partial turn-to move the pin G?into engagement with the retaining spring-G Pressure is' nowappliedwith-'one hand to j v y the lever J which controls themovement ofthe gauge bars J, J and, with the other hand, the clutch control handleLis rocked rearwardly to engage the clutch L withthe now moving gear If.A drivi 'igrconnection is thus established as before described, whichcauses rotation ofthe screw F to elevate the magazines 'As theijnagazines start to move up, the gauge bars are released, and continued pressure on'the lever J withdraws them to their inactive positionout of the path of the lugs A WVhen the magazine selected has reached apoint slightly above its normal operative position the lever- J? isreleased and the actuating springs j draw the gauge bars into their.active position with their upper ends beneaththe aligning lugs of saidmagazine. [l he'control handle L is .TlOW

When a change ofmagazines necessitatesa lowering of the shift frame, thelatter mustfirst be raised slightlyin the manner just stated to free-the gaugebar's'J, J "preparatory to their withdrawal. The clutch L 'is then movedinto engagement with'the gear L and held there until the desiredmagazine is arrested by the gauge bars the latter too meanwhile havingbeen'releasedin time to resume their normal position for engagement withtheahgning lugs A 'fof the selected ma azine. a

- Itwill be understood that while the shafts F and G, as hereinconstructed, constitute new elements that'a-re particularly adapted tothe proposed inechanism, the mainstrue- 'ture of the machine is leftunchangedandthe application of the present improvements to machines ofthe type described merelyinvolves a substitution of the bracket L, thedrive shaft G; and the shaft F for the old vparts previously employed.
